On the average lawn a top-dressing of manure at the rate of one-half to three-fourths cubic yards to five hundred square feet, of sheepmanure at the rate of five pounds for each one hundred square feet or ofbone meal at the rate of five pounds for each two hundred and fiftysquare feet, should be applied and raked into the surface of the lawn.Manure, whenever used, especially in the preparation of lawns in thespring, should be well rotted in order to avoid so far as possible thepresence of persistent weed seeds (such weeds as grow after the lawn isseeded). Bone meal and the types of dried manures commonly pur-chased on the market in bags do not bring into the lawn this objec-tionable feature. On the other hand, such concentrated fertilizers donot provide the humus which may be almost as essential as the foodcontained in the fertilizers. |
